SAN ANTONIO (AP) - The Spurs return to San Antonio needing just one more win over Miami to claim the NBA title. The celebration of a fifth league championship could come Sunday night in Game 5. The Spurs put themselves in a commanding position with a pair of blowout wins in Miami including last night. They are on the verge of avenging a loss to the Heat in the finals last year. But San Antonio could take a lesson from last year when they were a minute away from winning the title with a five-point lead, and blew it. Both teams are scheduled to take the day off.
